A semiconductor apparatus for use with a low voltage power supply includes an internal circuit that operates in synchronization with a first clock signal that is input from an external terminal or generated by a clock generating circuit, a voltage raising circuit for raising a power supply voltage in synchronization with a second clock signal whose pulse edge does not overlap with that of the first clock signal, and a constant voltage circuit for inputting an output voltage of the voltage raising circuit and supplying a constant voltage as a power supply voltage to the internal circuit.
